DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support mechanism for a snow brush device in a snow removal vehicle.

[0002]

2. Description of the Related Art A conventional snow brush apparatus is known which is disposed at a front portion of a snow removing vehicle. As a special example, it is disposed at an intermediate portion of the snow removing vehicle, that is, between a front wheel and a rear wheel. There are things.

[0003]

The above-mentioned prior art has the following problems. Originally, a snow plow is installed at the front of the snow removal vehicle to remove a large amount of snow for snow removal work, and a truck grader is provided at the middle of the snow removal vehicle to scrape the snow that has been compacted. However, this cannot be achieved with a conventional snowbrush device. The present application has been made in view of such problems of the related art, and an object of the present invention is to provide a solution that can solve such problems.

[0004]

Means for Solving the Problems In order to achieve the above object, the present invention is as follows. Of the present invention
The left and right brackets 1
3 and 14 are fixed by bolts, and the left arm 3 is connected to the left bracket 13 via the longitudinal axis 6.
The right front arm 4 is connected to the right arm 4 via a vertical axis 9, the right rear arm 5 is connected to the right front arm 4 via a vertical axis 10, and the front frame 2 </ b> A The right bracket 16 fixed to the front frame 2A is connected to the tip of the right rear arm 5 by the vertical axis 11, and is provided at the center of the inside of the left arm 3. Bracket 7A
A hydraulic cylinder 12 is stretched between the hydraulic cylinder 12 and the vertical axis 10, and the snow brush device 2 can be converted into a working posture and a forward posture by the expansion and contraction of the hydraulic cylinder 12. This is a supporting mechanism of a snow brush device configured to be able to work while maintaining an appropriate advancing angle so that snow scattered by snow removal does not directly adhere to the periphery thereof.

The operation is as follows. 1. The left arm 3, the right front arm 4, and the right rear arm 5 located on the left and right are moved by the expansion and contraction operation of the hydraulic cylinder 12. 2. 1 and 2 show a state in which the snowbrush device is stored,
That is, it is the forwarding posture of the snow removal vehicle. At this time, the hydraulic cylinder 12 is in the extended state, and when the hydraulic cylinder 12 is changed to the next working posture, the hydraulic cylinder 12 is in the contracted state as shown in FIG. 3 and FIG. Make a rightward turn. Further, the right front arm 4 makes a leftward turning operation with the vertical axis 9 as a fulcrum. 3. The right rear arm 5 turns to the right with the vertical axis 10 as a fulcrum. Therefore, the left bracket 15 moves rightward, and the right bracket 16 moves rightward and backward of the snow removal vehicle A. By the above operation, the brush 1 can maintain an appropriate advancing angle.

And the hydraulic cylinder 17
With the link 20 on the bottom side of the front frame 2A
Rotatably connected by a pin 24, the rod side scan bra
It is rotatably connected to the printer 2 by a pin 31. Ma
Also, the hydraulic cylinder 18 has a pin similar to the hydraulic cylinder 17.
Front frame 2A and snowboard with 28 and pin 32
The hydraulic syringe 1 is stretched between
The snowbrush device 2 is moved up and down by the expansion and contraction operation of 7, 18
To change the transporting posture and the working posture.
You.

【The invention's effect】 The present invention is configured as described above.
Has the following effects. 1. Separate snow removal equipment installed in front and center of snow removal vehicle
It is possible to In other words, the snow
-By installing a brush device, snow plows and
Track graders can be installed as before.
You. This allows for snow plows and track grays
Are located at the front and middle of the snowplow and at the rear.
It can be used properly with a snowbrush
This allows for efficient snow removal. Also, snow removal vehicles
Snow scattered from the snowbrush device installed at the rear of the car
Proper left and right position and advance so as not to adhere to both rear wheels etc.
The snow removal operation can be performed while holding the corner. 2. Left arm 3, right front arm 4, right rear arm 5-3
Arm and one hydraulic cylinder 12
The snowbrush device is connected to one control switch.
